Issue After Replacing Inverter Coolant Pump

Usually when you change this thing and you put the hoses back up connect everything up and your low on coolant You fill up the reservoir and then you ready the car get out stand in front of the inverter and look at listen to the pump You hear it sucking air and then all of a sudden it'll fill with water The noise will drop dramatically as will the level in the container No need to open the bleed screw when the level drops in the container fill it watch it a second It should level off and you should almost not hear the pump running at all turbulence is moot It should be almost non-existent I mean you really have to be looking in there maybe even with a light It is very faint this pump barely moves water or coolant It has to move the coolant so slow that it dwells in the core of the radiator so that the heat can be wicked away by the fan or forced air coming in the front of the car so there's no need for it to be whizzing around through the reservoir at 40 miles an hour more like about a half a mile an hour barely able to see that's correct so what are you saying You getting a code you still got the red light on the MFD the AM2 fuse is blown The pump is running you verify that with your hand on it If you squeeze the hoses going to the inverter pump You should hear the pump labor when you squeeze the hose that seems like everything is fine go for a drive and see what happens nothing's going to happen if it overheats a little overheat it'll get a little warm and you'll come home are you using fake pumps?

 

The pump may not work due to its own malfunction or when there is no power supply to it.
Have you checked the power supply and the fuse?
